i was hoping that as the smaller stuff was wearing down the big pieces would break for more of a time release effect. I'm thinking of going to a run 3 days add run 4 days then do cleanout. ill have to be carefull about adding water as with all the fines last time i tried it i didn't add water and ended up with way to thick a slurry.

might want to leave the denim off till it cools down that water mist might be refreshing in that heat.

at a 7 day cleanout my slurry doesn't feel gritty at all. so most of it does break down i would say less than 5 percent (the biggest of the chunks) are still there but settled near the bottom.

New fire pit. Sawed off(plasma cut) 41 inch hemispherical bowl to sort of a Wok shape. 36 inch bowl, 48 inch table top, 30 inch base. Has a 49" cover. That looks super clean and modern... Real clean curves and lines. Bowling ball? 🏆 bowling ball = next weeks tumbling rough. lol

I would think garnets would tumble to a shine with just about anything as they are from 6.5 to 8.5 hardness. don't know about the others. my non scientific rule of thumb would be the longer they take to round up the better the polish. I have some garnets in my 3lbs barrel right now. cant wait to see how they come out.

Will do same overdose on this one pound sphere shape. Has much deeper grind marks. Pretty sure the deeper grind marks will require a cup every 2 days for either 4 or 6 days. Perhaps longer. Will give notjustone 's bulk grit a try on some of these pre-grind overdose runs. Compare screened SiC 30 to his bulk stuff. ID on this rock greatly appreciated. I am going to try a run with less probably 60 percent full in at least 1 of my barrels when I do my cleanout this weekend. I'm finding the big chunks of sic are actually rounding off instead of breaking down. I seal them up and let them run for a week at a time with no additions. ive been running pretty full 75 to 80 percent in 8" pvc barrels at 37 rpm. or I may fire up the wood lathe and turn a larger drive pulley and speed up my bottom shafts. I'm not really sure if it cuts faster than 30 grit. but since its free and I still have a couple hundred pounds of it ill continue to use it.

I'm wondering if this is the same thing I have noticed recently. Only see it in clear parts of agate. Small crescent-shaped fractures for lack of a better word. Often only visible from one aspect. I have examined these with a 10 power loupe. They don't seem to be on the surface. I too thought they were from tumbling larger rocks in a high-speed Tumblr. But I check some of my older tumbles and still found these. Really don't know what they are. if your only seeing them in the clear parts could it be the material has little to no mineralization and they are tiny conchoidial fractures?

another thing to think about is that each color layer may have been days of shooting that same color over and over. so you would have to shoot each color for days to get the thickness in the bands.

I just use some of the plainer looking rocks bust them up smaller run lots of smalls. cant see adding ceramics or gravel just to make up volume or add smalls to the barrel.

I learn so much from all you guys and gals late at night and especially you Jim. Cant begin to thank you enough for all the knowledge and comraderie that you provide to all of us. Thanks !!
That diamond cup grinder does make tumbling a pleasure. Hell, in many cases a rock has to be ground done to way more than half it's original size to get all the defects out of it. Lot's of waste. But consider sawing the sweet spots out of a rock to get the best cabs...lots of waste too. In the coral rivers I will set a comfortable chair on a rock bar and hammer tumbles. So much coral. May only keep 20% of the rocks I chip off. The el primos. Instead of carrying back 10-20 pound coral heads in the boat and trashing most of it at home. Or sledge out primo core chunks. are you tossing a lot of the plain ones? that are solid enough to use as a supplement for ceramics?

i just got my vibe in middle of april. so a run every week for the past 7 or 8 weeks. minus 1 week when i didn't have enough out of coarse to fill it. i run a lot of mixed stuff so some shines better than others but if i take like stones. like say 2 nice hard pieces of well agatized pet wood for example and compare one from 1st batch to 1 from last batch the polish quality looks the same. seems if it was embedding the finish quality would get worse every week as more is embedded. plus i look at it like this. once the ao has rounded off its effectively no different than any other stone in your load. whereas the sic breaks down and stays sharp. rounded off ao would basically be microsmalls

as others have said the plastic piece (wire strain) is removable. squeeze it with pliers. snip your wires strip them back wire nut to new motor pop wire strain back in with a little more wire pushed through.

Thanks Randy. Not gettin a good shine really, I HAVE to get another drum for my UV10 dedicated to polish. The SiC just embeds in the HDPE so it's like having time released coarse grit. There's an idea for jamesp ..... Totally agree on the dedicated polish barrel. I don't have a dedicated polish barrel yet for the uv-10 but I only run the ao-80 seems like it breaks down enough it doesn't matter. ive never put sic in it though.

The drying process may be the key MrP jamesp Yes it is. Time & $................................MrP now with todays paints being 2 part urethanes you take the heat out of the equation with catalysts. but the cost is gonna be through the roof.

I didn't think of that the old baked on enamel or was it laquer finishes. probably lots of non automotive painting operations as most places that repaint cars vs assembly line painting wont have shelves or hanging apparatus for layers to get built up on.

makes one wonder what the good end of the rock looks like. if I'm looking at it right it looks like he started on the boring looking end. when I sent it to him I figured he would start on the other end run till the sheen ran out then chuck the bottom half.

I'd have to have a helper for the top shelf no doubt. Guess the client better have some neighbors to assist. Lots of young bucks at in-town. "Hey ! Come give me a hand !" I'm not shy. I was thinking of something like the tin smiths use for putting ductwork together. Add another crank in the middle to pull the load out, crank it down to the ground. I would just add a hf truck bed crane to the trailer and call it a day. odds are good you will be unloading at places where one of them cranes with little tires wont roll anyway. www.harborfreight.com/12-ton-capacity-pickup-truck-crane-with-cable-winch-60731.html or build your own its not super complicated. some square tube a jack and hand winch. you can make it longer to reach front and back. back in swing it out set it on the ground and off you go.
